描述
ISL9008A is a high performance single low noise, high PSRR LDO that delivers a continuous 150mA of load current. It has a low standby current and is stable with 1µF of MLCC output capacitance with an ESR of up to 200mΩ. The ISL9008A has a high PSRR of 65dB and output noise less than 45µVRMS. When coupled with a no load quiescent current of 46µA (typical), and 0. 5µA shutdown current, the ISL9008A is an ideal choice for portable wireless equipment. The ISL9008A comes in several fixed voltage options with ±1. 8% output voltage accuracy over-temperature, line and load. Other output voltage options may be available upon request.
